This carbine is one of over 11,000 altered and refurbished by the Springfield Armory around 1867-1874 with relined three-groove rifled barrels for use with both 56-52 "52 Spencer" and 56-50 "50 Spencer" ammunition, and fitted with a Stabler cut-off. It has the standard Spencer markings and sights, and the left of the stock behind the saddle bar is stamped with a "TJS" inspection cartouche. Absent rear sling swivel.

Fine, retains 30% arsenal refurbished blue finish on the barrel with scattered smooth brown patina on the balance, and 40% of the case colors strongest in protected areas with smooth gray patina and scattered mild freckling on the balance. Stock is fine as re-oiled, with defined edges, some scattered mild pressure dents and scratches, and a legible cartouche. Mechanically excellent.
